how to read selected node and its parent node values for treeview in asp.net in JAVAscript.
View 3 RepliesI have a treeview with four levels; parent, child, grandchild, great-grandchild. My selectednode is at the grandchild level.
What I'm trying to do is to create a new "Treeview" at the grandchild - NO, I dont wnat to create a new node to the "selectednode" (grandchild). So it should be somelike this:

How do I get the value of a treeview's selected node and it's children's values?
TextBox1.Text = TreeView1.SelectedNode.Text; doesn't do it.
I have a treeview and I am giving the node style in code behind.
Treeview design is as below:
<asp:TreeView ID="tvIARHierarchies" runat="server" NodeIndent="15" ShowExpandCollapse="true"
ShowLines="True" Width="98%" OnSelectedNodeChanged="tvIARHierarchies_SelectedNodeChanged">
<ParentNodeStyle Font-Bold="False" />
<HoverNodeStyle Font-Underline="True" ForeColor="#6666AA" />
<SelectedNodeStyle Font-Bold="true" BackColor="#6f9dd9" ForeColor="White" />
<RootNodeStyle />
<NodeStyle />
<LeafNodeStyle />
</asp:TreeView>
While populating the tree-view I have a requirement to bind the one particular level with a different colour. So, I am binding it as below
foreach (DataRow row in dr.GetChildRows("rsParentChild"))
{
TreeNode cChild;
if (row["NAME"].ToString() != "")
{
if (row["Level"].ToString().Trim() == "4")
{
string strColor = "DarkOrange";
string fname = "<font id=" + row["NAME"].ToString() + " color ='" + strColor + "'>" + row["NAME"].ToString() + "</font>";
cChild = new TreeNode(fname, row["ID"].ToString());
}
}
Now when the tree view loads, the required level 4 nodes are populated in DarkOrange. But, when any node is selected the backcolour changes as #6f9dd9 as per the style specified in the markup. But the fore-colour does not change.
Suppose I have a treeview, where each treenode contains an id for a different set of user controls. When the user clicks a node, these controls should be loaded to the page. As I understand the ASP page life cycle, dynamic controls should be added in the initialization stage, and postback events will fire later on.
So if the treeview click event happens after I need to add my controls, how do I dynamically add controls based on user postback events?
Edit: I tried the ArronLS:
What I did was add the node value to the session array, and use that when I do the init to choose which form elements to load to the controls of a placeholder control. On the treeview click event, I update the node in the session array, clear the old form elements in the placeholder, and add the new form elements to the controls. When the page is loaded again, it should now find the node at init time, so viewstate problems would be circumvented.
Now I haven't fully tested this yet, but there was another similar post that talks about the problems that might result with the viewstate. They suggest a solution that polls the Request[] part of the context (in their case the dropbox) within the Init control, manually handling some of the postback functionality.
My new question is how to I access the selected node in the treeview using the Request array?
Im using an asp.net treeview control and i managed to get code from these forums so that when i select a node no postback is done but i can access the selected node in my C# code behind pages by using javascript.
It works fine i can get the selected node by saying:
TreeNode t = TreeView1.SelectedNode;
and then displaying it to a label on an on click event of a button:
Label1.Text = t.Text;
But what i really need is to either display the node selected to a label (or textbox) or when a node is selected it needs to be highlighted so that the end user knows the option chosen is selected.
i ve used the following code to avoid postback and selected node style for treeview by using this im able to avoid postback but im not able to set selected node style.

I have a treeview control where I am dynamically selecting a node depending on user interaction. when a node is selected I want to be able to have the scrollbar go to the location of that selected node in the tree. The scrollbar is simply made by overflow:auto in the div tag where the treeview is located.
View 1 RepliesI don't want to use Sessions to handle each click event inside treeview selected node changed.Secondly, if you suggest me to use treenode.SelectedValue then I would say my values are dyanmically generated.Everytime a node a clicked, the selected node value is sent in the next request xml to get response and xml schema is different for each click. How do I handle this each click event other than using session variables. I thought of using Request.Item (and integrating with URL redirect property) but I don't want to use that.

On a treeview, you can collapse/expand the nodes by clicking the +/- icon.
I would like to know how I can also click the node text to achieve the same results.
I want to be able to click the node text to expand/collapse the node.
How can I do this in ASP.NET/C# ?
Does anyone know a way to limit the amount of text that is displayed by the Treeview control for a node?
I know there is a property to warp the text but I want to perhaps limit the text size to say 20 characrters?
We have an asp.net treeview control and a texarea. The childnodes of treeview need to be draggable and can be dropped into txtarea.
View 2 RepliesI've built a TreeView in ASP.NET 3.5 and it works great, except the expand and collapse images (which are 20px by 20px) do not align properly with the text in the nodes. Below is a screen shot of the applicable tree, with all items selected to allow you to see where the items are lined up. I need the text to be vertically centered (by one means or another) so it lines up with the center of its expand/collapse image.
I've tried numerous tricks to make this happen, including CSS, but can't seem to find the right technique.
I have a dynamic treeview that is filled from a SQL Server database.
I have an asp label on the same page as the treeview.
I would like to change the corresponding text of the label when I hover over each corresponding node of the treeview.
How can this be implemented?
